Replying to cork spins

okay i'm gonna be skiing for a week straight, and i need to know what you guys think i should work on, i know i want to get corks though. as of now i've got up to 7 and i'm gonna be trying 9s and maybe a 10 since there are bigger jumps where i'm going. but i really wanna get corks, however i dont know how i should do them, i know you drop the shoulder and spin, but what about hwen you're coming out of it? and what spin should i do when i try the first time?
